I cannot get my image resolution small enough to load on the auction site.
Everything I load is 1.4 megs or so and that is way too big!
I have been selling on EBAY but that is too commercial. I just want to have a little fun buying and selling.

You need to reduce the image size to around 900 pixels.
See this thread.

Edit, using the search function in the header bar and choosing "keyword" - Image size or resize or Irfanview will bring up many previous posts that should help.

re: HELP?? reducing the resolution of my images to fit the auction site

I tend to keep my images around 100KB.
As mentioned by Sheepshanks, the longest or widest measurements should not exceed 900 pixels. You can still get a great representative image within these parameters.

I use a scanner at 600dpi. I usually still have to scale down the image a bit. If you are using a camera you will need to use a software utility to shrink your images.

I believe the critical issues for image uploading is that an image can be a maximum of 1400 pixels wide by 1230 pixel high. I don't know where those limits came from but as long as your image does not exceed those, it will upload. This effectively limits the weight (bytes) of a file to about 600Kb.

From the auction tutorial:-

Quote:

"IMPORTANT! The most common reason for an image not uploading to the Stamporama server is because the size of the image is too large. Make sure that the image is no larger than 1400 by 1230 pixels."


Edit
Just to add that smauggie's image above comes in at 571 x 703 pixels, that is, at least, according to Irfanview.

Here is Smauggie's image in a low-res version, same dimensions but only 49 KB; I used Pixelmator (a low-cost competitor of Photoshop for use on Apple computers):

It's important to note that "low res" does not mean poor image quality if it's to be used only on line.

Bobstamp are you sure you have put up the resized image as I get the same pixels as smauggies original.

He didn't change the size, only the jpeg image quality.

As Smauggie said, I lowered the resolution (not the dimensions) from 600 dpi to 72 dpi. 72 dpi is all you need for use on line.

To post quality images you need
1. A dedicated scanner - not these all-in-one and definitely not a hand held phone
2. Dedicated scanning software - not what comes with the scanner
3. Time getting the settings right - lots of time and then saving these profiles - I have different one depending on the type of image or text
4. Learning about the different image types and how they effect quality and size

The above image was scanned at 1200DPI (1400 X 1120 and only 400Kb in size) - High DPI is NOT a factor in quality images. It was not manipulated with any "editing" software. Comes directly out of the scanner software

same image scanned at 150DPI - 40Kb in size

If you are selling stamps, quality images = more sales
